Ohm-r

¿Do you know how many ohms and tolerance have your resistance? With ohm-r you just have to provide the colors and you are done!

Installation

$ npm install ohm-r -g

Quick Start

The quickest way to get started with ohm-r is providing the colors of your resistance like:

$ ohm-r yellow violet orange gold

You will get the following output:

Ohms: 47,000
Tolerance:
    Min: 44,650
    Max: 49,350

Module

You can use it as a module like:

    var ohm = require("ohm-r");
 
    var result = ohm.calc("yellow", "violet", "orange", "gold");
 
    console.log(result); //{ ohms : 47000, tolerance : { min : 44650, max : 49350 } }

Typescript

Ohm-r has support with Typescript, that's why you can get intellisense and autocomple for colors like:

    var ohm = require("ohm-r");
 
    var result = ohm.calc(ohm.colors.YELLOW, ohm.colors.VIOLET, ohm.colors.ORANGE, ohm.colors.GOLD);
 
    console.log(result); //{ ohms : 47000, tolerance : { min : 44650, max : 49350 } }

Validation

• The calc method requires minimum 4 colors, otherwise it will raise an exception.

Error: The resistance must have at least 4 colors.

• An invalid color will raise an exception too.

    var ohm = require("ohm-r");
 
    var result = ohm.calc("pink", ohm.colors.VIOLET, ohm.colors.ORANGE, ohm.colors.GOLD);

Error: The color "pink" does not exist.

Inspiration

This module is inspirated by the common mistake of forgetting the value of the colors in a resistance.
